ATENT CHAIN-PUMP BUCKET.

SPECIFICATION forming part of Letters Patent No. 316,005, dated April24, 1885.

7 Application filed June 19, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, RUFUs M. BROOKS, a citi zen of the United States,residing at Greeley, in the county of Anderson and State of Kansas, haveinvented certain new and useful Improvements in Chain-Pump Buckets; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates to buckets for chainpumps in which the water israised through a tube by means of a series of buckets made to fit thebore thereof; and it consists in the novel construction, combination,and arrangement of parts, as will be hereinafter more fully describedand claimed.

In the drawings, Figure 1 is a perspective view of one of my buckets.Fig. 2 is a detail plan view of same with one end plate removed andshowing one of the packing-sections in detail. Fig. 3 is a verticalsection of the bucket. Fig. 4 is a detail view, showing the inner sideof one of the end plates, all of which will be described.

The link A is preferably made angular in cross-section, as shown in Fig.2, and has formed transversely through it openings at a, arranged atright angles to each other, as shown. The end plates, B, are placed orformed on the link near the opposite end of the latter, and areprovidedon their inner faces with grooves or slots 6, the said slotsbeing formed in their respective end plates in line at right angles toeach other. To illustrate, for example, the grooves in the end platesare formed parallel with the adjacent transverse opening through thelink, as will be understood fronu Fig. 3.

The packing-sections G are preferably four in number, and arranged inpairs, as shown. They are formed of segments having their bases formedapproximately straight and through the center of the curve of the crown,and when placed on the link the base-lines of each pair are at rightangles with the similar lines of the other pair. Thus the crowns ofonepair lap the joints of the other and a complete close packing isfurnished.

The faces of the sections next the end plate are provided withprojections or studs D, which extend into the grooves 12 of the endplate and hold the sections from detachment, and yet permit theirlateral adjustment to bind closely the walls of the tube. The inner edgeor base of these sections is formed with a slot or mortise, O, fitted tothe link, as shown in Fig. 1, so as to prevent the section fromrevolving on the link. Springs E are inserted through the openings a a,and bear at their opposite ends against the inner sides of the sections,as will be understood from Figs. 2 and 3, thus giving said sections anoutward tension.

Where so desired, instead of inserting the spring through the link andusing one spring for each pair, separate springs may be employed foreach section and made to bear between the same and the link, and theform of spring may be coil or any other suitable one desired. I prefer,however, to construct and arrange the spring as shown and beforedescribed, and in order to secure a better action of the springs Iprefer to fit their ends into sockets 6, formed in the inner sides ofthe sections, as shown in Fig. 3.

It will be appreciated that, instead of forming the studs on thesections and the grooves in the end plates, the order may be reversedwithout departing from the spirit of my invention. I prefer to form theend plates separate from the link, as shown 5 but where so desired theymay be formed integral therewith, in which case it will be desirable toform the stud or projection detached from the plate and inserted througha slot through the plates; or the groove may be formed in the sectionsand a screw turned through the end plate to serve as a stud.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A chain-pump bucket composed of a stem IOO posed of the link, the endplates provided on their inner faces with slots, the paoking-seci 5tions having their faces next said plates provided with studs orprojections adapted to enter the slots in said plates, and the springs,substantially as set forth;

In testimony whereof I affiX my signature in 20 presence of twowitnesses.
